Hitachi 50ux58b Red light on front power panel comes on when tv is plugged in for a few seconds then shuts off .I unplugged TV took the TV apart plugged TV in and looked at circuit boards three green led iights come on followed by a red light that has d912 protected led written by it then shuts off

i have the same problem red light comes on for a second then goes off that is it I can't get it to do anything else.i have the same problem red light comes on for a second then goes off that is it I can't get it to do anything else.

If you have Hitachi model number 50UX58B, 60UX58B, 50UX58K, 60UX58K, 50SBX78B or 60SBX78B and you have the following symptoms you may want to grab a repair kit from www.TvRepairKits.com. They have put together a kit that includes the parts and instructions to fix these models. This is a fairly common problem with the above model numbers. It is typically caused by a blown capacitor and pico fuse. Again, you can get a kit from the above address. Here are the symptoms...

Primary Symptom: No Audio or Video. Power light will come on briefly then shut off.Other Possible Symptoms : The green LEDs on the circuit board light up for a few seconds then turn off.

It's possible that the Convergence IC's are causing a shutdown of the power supply. Also on this model, there have been problems with:
C707 - 1000pf @ 2kv Cermaic Disc Cap (normally a small blue one) Hitachi Part # 0244211.
I901 - A STRM6811a Reg Ic and
E994 - 2.0 Amp Circuit Protector (Pico Fuse) having a high failure rate. If the 2 amp pico fuse was good, and the capacitor looked OK, then I would check the convergence circuit board. There are many other parts that can also cause shutdown problems, however.

power in the tv has nothing related with the DVD. The tv has to have raster (white screen) even without signal (cable, DVD, others) if the tv alone is just having the led flashing and neither sound nor video (black screen) The tv has a short circuit in some of the boards that are part of the tv system. the blinking is part of a protection when the tv was created in the factory. Refer to the technician to repair this problem.

Yes, i just answered a post to another problem simular to this, it is the POWER SUPPLY, it was blown either from an electric surge, caused by storms or ground faults, or it was shorted. you need to get a new one, have a professional install it for you.

I have seen that symptom many times. Most likely, the little blue capacitor next to the horizontal output transistor has shorted and popped the main B+ fuse. This is very common in those Hitachi projection sets. These parts should be replaced by a tech familiar with Hitachi projection sets.
